It is a maddening and frustrating situation. These are people who were there observing and documenting. None of the arrest reports for the six journalists makes any specific allegations about what any of them are supposed to have done wrong. Get used to what happened. The US in no longer a free run terratory for journalists, With all the fake news that has been spread by every enitity of the government and the press it very well may become a journalist free country till the news services figure out to tell it as it happened and not make their own news stories that never happened.
Journalist should be subject to the same laws as other citizens as far as doing something illegal. If they are really caught up in the midst of a riot, I don't see why they or anyone else should be held after initial questioning. We need more details regarding the happenings over the week.
Journalists being jailed for covering news that is unpopular to the President is illegal and unconstitutional. Freedom of the press is a liberty that should not be taken lightly and no president should have the power to distort this liberty. Donald Trump is already acting out what most Americans feared he would.
If a journalists is simply covering a live event, like a protests or violent demonstration, the journalist should not be prosecuted for any crimes. However, if the journalist is trying to spark unrest, then he should be held liable. In the case of the journalists arrested for covering inauguration unrest, they were just doing their jobs.
